Nonlinear Spline Finite Element Analysis of Reinforced Concrete Slab

本文运用样条有限元技术和增量等刚度迭代法对钢筋混凝上板进行了非线性分析,提出了加速收敛的方法。与常规有限元法比较,减少了工作量和计算机内存且计算精度较高。

In this paper, spline finite element method and the incremental iteration with initial stiffness are applied to nonlinear analysis of reinforced concrete slabs. A technique for accelerating the convergence is presented. Compared with the ordinary finite element analysis, the suggested method can obtain the results with higher accuracy by less computer time and memories.
